| Fez-se o levantamento florístico da vegetação arbórea da floresta mesófila do Parque Estadual do Morro do Diabo, Município de Teodoro Sampaio, Estado de São Paulo (22º30'S, 52º20'W) pelos métodos de quadrantes e parcelas, incluindo as árvores com diâmetro à altura do peito igual ou superior a 10 cm. A utilização dos dois métodos deu-se em função das características fisionômicas, solo e drenagem dos locais amostrados. O método de quadrante envolveu 462 pontos com intervalos de 30 m., e o método de parcelas ca. 26.900 m² (ca. 2,7 ha.). Os parâmetros fitossociológicos serão abordados em futuros trabalhos. Os dados florísticos subsidiaram o reassentamento dos grupos faunísticos, em especial o Leontopithecus chrysopygus Mikan, 1823 (mico-leão-preto), dentro das... |

| The decay of seeds is irreversible and at best can only be delayed by applying techniques that reduce the velocity of the metabolic reactions involved. There is little information on the biochemistry of tropical forest tree seeds related to their storability. It was investigated the influence of the composition of lipids and soluble sugars of two storage compartments, the cotyledons and the embryonic axis, of Melanoxylon brauna Schot. (Leguminosae- Caesalpinioideae), a hardwood known as black brauna, seeds stored at 20 ºC for 0, 3, 6, 9 and 12 months (natural ageing) and for 0, 24, 48, 72 and 96 hours at 40 ºC (accelerated ageing). The levels of fatty acids and monosaccharides varied differentially in each of the embryo storage compartments. Changes in... |

| El mantillo y horizontes de fermentación (CF) es un reservorio dinámico de carbono (C) en suelos forestales. Las metodologías que cuantifican la emisión de CO2 por la descomposición son escasas y requieren periodos largos de medición. Se requieren métodos para poder generar información de la emisión de CO2 de éstas capas orgánicas en tiempos cortos de medición. Los objetivos fueron: generar un protocolo para la medición de la emisión de CO2 por la descomposición de mantillo y CF con un respirómetro manométrico (OxiTop ®). Medir los reservorios de C de mantillo y CF de bosques con diferentes condiciones. Medir la emisión de CO2 del mantillo y CF y las tasas de descomposición con un respirómetro. Analizar las características químicas de los mantillos y... |

| Farmers’ practices in the management of agricultural landscapes influence biodiversity with implications for livelihoods, ecosystem service provision, and biodiversity conservation. In this study, we examined how smallholding farmers in an agriculture-forest mosaic landscape in southwestern Ethiopia manage trees and forests with regard to a few selected ecosystem services and disservices that they highlighted as “beneficial” or “problematic.” Qualitative and quantitative data were collected from six villages, located both near and far from forest, using participatory field mapping and semistructured interviews, tree species inventory, focus group discussions, and observation. The study showed that... |

| This study presents an approach to analyzing decentralized forestry and natural resource management and land property rights issues, and catalyzing collective action among villages and district governments. It focuses on understanding the current policies governing local people’s access to property rights and decision making processes, and learning how collective action among community groups and interaction among stakeholders can enhance local people’s rights over lands, resources, and policy processes for development. The authors applied participatory action research in two villages, one each in the Bungo and Tanjabbar districts of Jambi province (Sumatra), Indonesia, to facilitate identification of priorities through phases of planning, action,... |

| The eucalyptus plantations constitute a major segment of the Agribusiness System of Forestry in Mato Grosso do Sul, thus, this study has focused primarily examine the competitiveness of this segment by applying a quantitative methodology for analyzing economic results called Quasi-Income, stating ultimately its competitiveness. Moreover, to capture the information held visiting the institutional actors directly connected to the system, which also allowed the identification of strengths – such as a favorable climate, large areas for forest planting , policy environment, wellstructured and very active, new arrivals agents that complement the chains, rates of return and profitability positive; and negative – failing infrastructure for disposal of raw... |
